6 Claims. (Cl. 214-518) This invention relates to dump or disposalvehicles or trucks and, more particularly, to a novel compartmentedconstruction therefor.

In many instances, refuse such as garbage, ashes,

papers, etc. is picked up and disposed of by private contractors. Insome municipalities, private or contract refuse collection supplementsmunicipal collection services.

The cost of operating private collection services have increased to suchan extent that the profit margin is substantially reduced. Such costsinclude capital investment in collection equipment, amortization ofcapital costs, labor, equipment operation and maintenance costs, andfees for the use of dumping areas. As a result of the decreasing profitmargin, intensive investigations have been made of all possible sourcesof increased revenue or reduced costs.

One possible source of increased revenue is the sale of re-usable wastesuch as paper, paperboard and corrugated boxboard. However, it is notpossible for general refuse collection services to take full advantageof this source of revenue due to the relatively high cost of separatingsalable waste from non-salable waste.

Modern dump trucks for collecting waste include a loading sectionpivoted on the rear of the truck body and including a receiving hopperat a lowelevation into which the waste is dumped. Rotary paddles in thishopper push the waste forwardly toward the main body where the waste isengaged by a reciprocable or oscillatable pusher which packs the wasteinto the truck body. The loading section acts as closure for the rear ofthe body and, when it is desired to dump the waste, the loading sectionis swung to an open position as the truck body is tilted to the dumpingposition.

In accordance with the present invention, separation of the salablerefuse from the non-salable is facilitated and made economicallyfeasible by dividing the hopper and the truck body into two or morecompartments with each hopper compartment being longitudinally alignedwith a corresponding truck compartment. With this 'arrangement, salablerefuse, suchas paper, etc. can be dumped into one hopper compartment andnon-salable refuse into the other hopper compartment.

Because of trade conditions, a preferred arrangement involves threehopper and body compartments. Of the three compartments, one receiveswaste paper, a second receives paperboard or boxboard, such ascorrugated drawing.

Re. 24,959 Ressued Mar. 28, 1961 ICC board, and the third receivesnon-salable refuse. Ihe economic reason for this is that higher pricesmay be obtained for corrugated boxboard as compared to prices receivedfor other waste paper.

To permitv selective dumping of the salable and nonsalable refuse, asufficient number of removable body compartment closure plates areprovided so that, during dumping, the back ends of all except one of thebody compartments are sealed off. With a two compartment arrangement,only one closure plate is necessary, whereas two plates are necessaryfor a three compartment construction.

These closure plates are made of lightweight material and have a widthof the order of that of the compartments and a height of the order ofthe body height. The plates are suitably stored in a rack securedbeneath the refuse receiving hopper and the truck body. When the load isto be dumped, the loading Section is rst pivoted out of the way beforethe body is tilted. The selected compartment or compartments are thenclosed by hooking a closure plate to the back of the body at the upperedge thereof and then latching the lower edge of the plate to the floorof the body. When the body is tilted, only the material in theopen-ended compartments will be dumped. After each use, the plates areremoved and stored in the holding rack.

For an understanding of the invention principles, reference is made tothe following description of a typical embodiment thereof as illustratedin the accompanying In the drawing:

Fig. 1 is a rear elevation view of a dump truck embodying the invention;

Fig. 2 is a rear elevation view of the truck body;

Figs. 3 through 6 are somewhat diagrammatic partial vertical sectionalviews illustrating the loading and packaging action.

Fig. 7 is a side elevation view illustrating the dumping action; and

Fig. 8 is a sectional view on the line 8 8 of Fig. 2.

Referringto the drawing, the invention is illustrated as incorporated ina trade waste collection and dump truck comprising a body '10 tiltablysupported, as at 11, upon a chassis 12 having a driving ca-b 13 fandroad wheels 14. The truck illustrated by way of example yonly is knownas the Load Packer 500 manufactured by Gar Wood Industries, Inc. ofWayne, Michigan, and Richmond, California.

The rear end of body 10 is open, but is normally closed by a tail gatesection 15 pivoted to the rear upper edge of body 10 as at 16. Referringto Fig. 7, in dumping a load from body 10, tail gate section 15 is firstswung to the position 15 relative to body 10 and then body 10 is tiltedabout axis 11 to the position 10'.

Referring more particularly to Figs. 3-7, tail gate section 15 has itslower end shaped to form a semicylindrical hopper 17 to which access isprovided by raising a gate or door 18 which may be latched in the openposition. A rotary panel 20 is rotatably mounted in hopper 17 on stubaxles 21 on the side Walls 22 of the hopper. Panel 20 cooperates with apacking panel 25 oscillatably mounted in tail gate section 15 foroscillation about an axis 23, panel 25 being powered by an actuator 24.

Figs. 3-6 show the cycle sequence of loading and packing. In the loadingposition of Fig. 3 panel' 20 ex@ tends forwardly substantiallyhorizontally so that full access is provided to hopper 17, and panel 25is swung in against the load. When hopper 17 is fully loaded, thepacking cycle is started as shown in Fig. 4. Rotary panel 20 is rotatedcounter-clockwise to sweep the load toward body 10, with packing panel25 moving into the position of Fig. 4 after rotary panel 20 has moved inexcess of 90 degrees from the position of Fig. 3.

When panel 20 reaches the position of Fig. 5, panel 25 is swungcounter-clockwise to sweep the load from panel 20 into body 10 andcompress it against material already in the body. Panels 20 and 25 thenremain in the position of Fig. 6 until the next load pick-up.

- In accordance with the present invention, separation of salable fromunsalable trade waste during loading, and subdivision 'of the salabletrade waste if desired, is provided by dividing hopper 17 into threesubstantially equal width compartments by means of semi-circular parti-While a specific embodiment of the invention has been shown anddescribed in detail to illustrate the apterial storage body tiltablymounted on said chassis for tions 30 welded o1' otherwisepermanentlysecured in the l aligned with a partition 30 and extending the fulllength and height of the body. Partitions 35 may be welded, for example,to angles 36 running along the floor, roof and front wall of the body.

To accommodate partitions 30, rotary panel 20 may be divided into threepanels, each operating in a different hopper compartment, as by formingthis panel with slots 31 at each partition. The load sweeping andpacking operation takes place in the same manner as described `for Figs.3-7, as packing panel 25 clears the upper edges of partitions 30.

For selective dumping of the body compartments, removable closure plates40 are provided each having substantially the width of a bodycompartment and somewhat longer than the height'of body 10. Normally,panels or plates 40v are stored in a rack formed by a pair of channelsor angles 41 secured beneath hopper 17 and body 10. To secure the plates40 in compartment closing position, a downwardly facing channel 42 issecured along the rear of the roof of body 10. Each plate 40, at adistance from its upper edge substantially equal to the height of body10, has an angle `4? extending along its inner surface. To place a plate40 in position, lts upper edge is set into channel 42 and the plate isswung inwardly so that angle 43 rests on body floor 28.

To lock the plates 40, pairs of screw clamps 45 are hinged to theunderside of iloor 2 8 adjacent each side of a compartment and near therear edge of the body. The lower edge of each plate 40 is provided witha palr vof downwardly opening slots 44 each aligned with a clamp 45.With a plate 40 in position and with angle 43 resting on oor 28, clamps45 are swung up 1nto slots 45 and tightened. These clamps 45 may be thesame type as provided to draw tailgate 15 against the moisture sealinggasket around the rear edges of body 10. Plates 40 are preferablystiffened by members 46 welded across the outer surface thereof. Y

It should be noted that except for the compartmentation provisions andthe closure plates 40 and their storage and latching means, the truck isof known construction. In eecting the compartmentation, the partitions35 are preferably vertically aligned with the usual intermediatereinforcing members extending longitudinally beneath floor 28.

By the described construction, collection of separated -trade waste canbe elected by one truck and crew as compared with two trucks and crewsthat would otherwise be required to make separated collections ofsalable and non-salable waste. Generally, the salable waste is presentlycollected in an open top truck which may have a partition extendingacross its vbody intermediate of the l ends thereof.
